I want to plot all of my original data as a scatter plot onto the biplot created by PCA.

Michelle, the whole point of PCA is to create a new coordinate system. Plotting the original data in that coordinate system doesn't make sense. If you've done PCA, you must have the scores for your original data -- the scores are the original data transformed into the new coordinate system. Use BIPLOT to plot those - there's an optional parameter to do that.
Hope this helps.
